LOCOMOTIVE H EAD-LIGHT.

SPECIFICATION forming part of Letters Patent No. 365,112, dated June 21,1887.

Application filed June 3, 1886.

To all whom it may concern:

Be it known that we, lRvIN A. WILLI.-\Ms and CHARLES I. WILLL-mrs,citizens of the United States, residing at Utica, in the county ofOneida and State of New York, have invented certain new and usefulImprovements in Locomotive Head-Lights; and we do hereby declare thefollowing to be a full, clear, and exact description of theinvention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention consists in certain construe tions and combinations ofparts in a locomotive head-light, as will be hereinafterdescribed, andpointed out in the claims, whereby such headlights are greatly improvedfor giving signals and indications to engineers or train men.

In the accompanying drawings, Figure l is a perspective view of ourimproved signaling and indicating headlight with a portion of thereflector and bu rner-ease broken away, so as to show a front top signalor indicator, an auxiliary reflector, and curtain, as employed by us.Fig. 2 is a vertical central section of a head-light similar to thatshown in Fig. I, but modified in construction by having a bottom signaland auxiliary reflector added to it. Fig. 3 is a vertical sectionshowing the head light, Fig. 1, modified by having the curtain placedoutside of the reflector and burnercase. Fig. 4 is a front view of thehead-light shown in Fig. 1, modified by having front side signals orindicators applied to it, the numbers of said signals being placed ineither vertical or horizontal lines, as shown by full black lines and bydotted lines. Fig. 5 is a horizontal section of Fig. 4. Fig. 6 is avertical section of the head-light with the curtain removed. Fig. 7 is afront view of the curtain and cords for operating it and a portion ofthe reflector and burner-case in vertical section.

A in the drawings, Figs. 1, 2, 8, t, and 6, is the reflector andburner-case; B, the main retlector; C, the burner; D, an ordinary sidesignal or indicator; E, a top front signal or indicator; F, an auxiliaryreflector; G, a curtain; and H, a chamber in which the front signal orindicator, E, may be placed.

The signal or indicator chamber is placed on the outside of thereflector and burner-case and in communication with said case, and theSerial No. 204, 003.

(No modvl.)

signal or indicator is set therein forward of the main reflector andoutside of the front of the main reflector. The signal or indicatingchamber serves the purpose not only of hold ing the signals orindicators, but may be made to serve for receiving and concentrating andreflecting the light from the burner and main reflector upon the signalsor indicators, this latter result being effected by giving a properreflecting shape, as shown, to the back or top of the chamber, andconstructing the inside surface of the chamber either of some brightreflecting material or painting said surface white, the latter modeserving substantially the same purpose as the bright-surfaced matcrial.

The auxiliary reflector F is used for reflecting the light received fromthe main reflector B and burner G on the reflecting-surface of thesignal orindicator chamber and therefrom 011 the signal or indicator,and is madeof the form shown, or of any other suitable shape, and it isfastened on the inside of the case, partly in front of the mainreflector, overlap ping it to a small extent, so as to catch upon itssurface a portion of the main reflector and burner light, which is thencast on the surface of the signal or indicator chamber and there fromupon the signal. The auxiliary reflectorthus overlapping the mainreflector to take the light for the signal or indicator, is a veryimportant feature of our invention in connection with other parts, as bythis construction a small portion of the main reflectors light isutilized for this purpose, and we save the necessity of an extrareflector and burner to cast light on the auxiliary reflector and signalor indicator.

The curtain G is used to shut off the light from the head-light, and bypreference it is fastened inside of the reflector and burner-case A, infront of the main reflector B and burner O and behind the large frontglass, I, as shown in Figs. 1 and 2; but, if desired, it can be placedoutside of the case over the large front glass, I, as shown in Fig. 3.

The obscuring of the light from the head.- light indicates to anengineer of an approaching train that the main track, which is asingletrack, is clean. The train, with its head-light obscured, is run on aside track, so as to allow the train on the main track to pass.

As the engineer of the approaching train passes the one on the sidetrack, he sees the front top signal .or indicator, E, which indicates tohim what locomotive and train he is passing. The light from thehead-light being shut off from view by the curtain, it does notinterfere with the light on the said signal or indicator, nor obscureit, but makes it more brilliant to b seen by the engineers or train-men.

This use of the curtain, in combination with a front signal or indicatorand with a signalchamber and auxiliary reflector, is a very importantfeature of our invention; and while we are aware that a curtain forshutting off the light of a head-light is not new we believesneh acurtain has never been used in connection with an auxiliary reflectorand a front signal or indicator which designates perfectly to engineersor train-men the number or name of a locomotive they are passing. Whenthe curtain is placed inside of the reflector and burnercase, it isshielded and protected, while raised from the reflector and burner heatby the aux,- iliary reflector.

The curtain may be arranged on a roller, J, either outside or inside thecase A, and lowered by two cords, a a, connected to lower end of thecurtain and passed under pulleys a a and then united as a single cord,at, having a pull-ring, a at its terminus, as shown in Fig. 8. By thisarrangement the curtain can be lowered by a sidewise pull on the cord aOther methods of lowering the curtain may be adopted; but thisarrangement is a very convenient one for a head-light. For raising thecurtain, an ordinary spring within the roller may be adopted; orcrank-handles, or other known means, may be applied to the ends of theroller for that purpose.

The curtain may be made of an opaque material, so as to shut off thelight of the head light at the glass I completely; or it may be made ofa translucent material, so as to show transparent as well as dim, or ina measure obscure the light. The translucent-curtain may be of a red,green, or any color which will show the color under the action of thelight behind it in the night, and also be visible by reason of the colorin the day when the light is out. o

By having the curtain colored, as described, 1 it can of itself be usedas a signal opposite the glass I and forward of the main reflector andburner, while the signal or indicator E is also used for its specialpurpose.

In the different views of the drawings we have illustrated how ourcombination of front signal orindicator,signalorindicator chamber, andauxiliary reflector, and also the same in combination with the curtain,can be employed either at the top, bottom, or front sides of thereflector and burner-case, and also how it may be used in connectionwith a side signal or indicator, D, and light catcher or shield K on thelongitudinal side of the reflector and burner-case, and with an ordinaryrear reflector, K, upon which light is cast by the burner burner, afront signal or indicator chamber located forward of themain reflector,having a reflecting-surface, andan auxiliary reflector placed forward ofthe main reflector, said parts being constructed and arrangedsubstantially as described and shown, theauxiliary reflector beingplaced so as to slightly overlap the front of the main reflector and inrear of thelarge front glass,there being aclear open space between thefront edge of the main reflector and the front side of thereflector-case, with which said signal-chamber communicates, thearrangement being such that the burner-light is exposed directly to thesignal, while' the auxiliary reflector, in conjunction with thereflectingsurface'of the signal-chamber and main reflector, throws lightupon said signal, substantially as described and shown.

2. The combinatioinwith a locomotive headlight, of a curtain, areflector-case, amain reflector, a burner, a front signal orindicatorchamber located forward of the main reflector, havinga-refleeting-surface, and an auxiliary reflector placed forward of themain reflector, said parts being constructed and arranged substantiallyas described and shown, the auxiliary reflector being placed so as toslightly overlap the front of the main reflector and in rear of thelarge front glass, there being a clear open space between the front edgeof the main reflector and the front side of the reflector-case,withwhich said signal-chambercommunicates, the arrangement being suchthat the burnerlight is exposeddirectly to the signal, while theauxiliary reflector, in conjunction with the refleeting-surface ofthesignal-ehamber and main reflector, throws light upon said signal,substantiall y as described and shown.

In testimonywhereof we afflx our signatures in presence of twowitnesses.
